PolyCap TF 36 PTFE Capsule Filter, 1 piece SKU: 6700-3602

PTFE Capsule Filters - 6700-3602

From HPLC mobile phase preparation to process gas venting, PTFE capsule filters handle the chemically aggressive applications where other membrane materials degrade or fail. Furthermore, PTFE membrane stability at elevated temperatures supports both liquid filtration and sterile gas venting applications, with capsule construction rated for the operating pressures encountered in process-scale systems. For this reason, the outcome is a validated filtration barrier that arrives ready for process integration, supporting the single-use manufacturing strategies adopted by modern pharmaceutical and biotechnology facilities.

Key PTFE Membrane Characteristics

• The hydrophobic PTFE membrane serves both liquid solvent filtration and sterile gas venting applications, with alcohol pre-wetting required only for aqueous solution processing.
• PTFE membrane chemistry withstands autoclave temperatures, supporting sterilization protocols where both the membrane and housing construction are rated for steam exposure.
• Maximum operating pressure of 60 psi provides the differential pressure capacity needed for sustained filtration of viscous solutions and high-flow process streams.
• The pleated PTFE membrane configuration within the capsule housing provides sufficient surface area for production-scale solvent filtration without the pressure drops associated with flat disc PTFE devices.
• PTFE capsule filters maintain mechanical integrity and retention performance at temperatures exceeding those tolerated by PES, PVDF, or nylon membranes, supporting high-temperature process filtration.

Key Capsule Construction Features

• Single-use polypropylene capsule construction eliminates cleaning validation requirements, reducing the regulatory burden and turnaround time associated with reusable stainless steel filter housings.
• Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.
• Polypropylene capsule housing provides broad chemical compatibility from pH 1 to 14, resisting the acids, bases, and process chemicals that degrade alternative housing materials.
• Polypropylene capsule housing supports autoclave sterilization at 121 degrees Celsius and withstands gamma irradiation exposure, accommodating both user-sterilized and factory-sterilized device configurations.

As batch volumes and regulatory expectations continue to grow, your capsule filter selection becomes a process design decision that affects sterility assurance, product recovery, and operational cost per liter filtered. For exactly this reason, for laboratories and production facilities filtering HPLC mobile phases, aggressive chemicals, or sterile gases, PTFE capsule filters provide the chemical inertness your purity standards demand. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
